Mass, a corporation of Massachusetts Application August 29, 1933, SerialNo. 687,319 g y 19 Claims.

. This invention relates to protector mechanism for looms and it is thegeneral object of themvention to provide means to protect at any one of.a plurality of positions along the shuttle box.

The invention contemplates the use of a flexible element, as a belt,toform one side of the shuttle box, instead of the usual binder. Theordinary protector finger bears against the binderand is pushed out whenthe shuttle reaches a given point in its travel along the lay. If it isdesired to protectlate in the loomcycle. this can be accomplished onlyby bending the binder to engage the shuttle later. This adjustment necessarily alters the checking of the shuttle. It is an important object ofmy inventionto provide a protector indicator movable to various. posi- Itions along afiexible shuttle check the effective length of which is notmaterially changed by the' setting of the indicator, or time ofprotecting.

By such. an arrangement the same amount of surfacecontact between theshuttle and its check is maintained regardless of the adjustment forprotection.

e The travelling shuttle checking surface can be arranged to move freelyin one direction and against resistance in the other direction, and

furthermore the free motion may be either toward or away from the centerof the loom. It is a further object of my invention to render theconnected to resist the shuttle as it enters the box.

With these and other objects in view which will appear as thedescription proceeds, my invention residesin the combination andarrangement of partsjhereinafter described and set forth in'the claims.

Inthe, accompanying drawings, wherein a convenient embodiment of myinvention is set forth, Fig. 1 is atop plan viewof a lay end having myinvention applied to protect/early and withthe shuttle checking beltresisting boxing of the shuttle, t g ,Fig. 2 is a vertical section online 2-2, Fig. 1, Fig; 3 is a front elevation ofthe structureshown'plate I l in front of reed l and lies against the shuttle, asv viewedin Fig. 2.

the lay has a stud'45' for the pulley 43.

Referring to the drawings, thelay'm has a-box front H behind whichmoves'picker l2 and picker stick 13. The shuttle S moves alongthe racebox front when box is as shown in dottedlines in Fig. 1. p a i Aprotectordagger l6 coacts' as usual with a hunter I! to stop the loomwhen the shuttleffails to reach a predetermined pointalong the lay at agiven point in the loom cycle; The protector rod I8 to which the daggeris secured rocks in bearings on the lay, one of which is shown at l9,while a similar bearing not shown is at the opposite end o-fathe lay. AnarmZl adj'ustably secured to the rod has a finger 22iprojectinginto; afork 23 on a second arm Zialdjustably secured to a small shaft25.'The'latter is rotatable relatively tothe lay in bearings 26 and is heldagainst end motion by collars 2'1 fixed thereto. 30

An arm 28 is mounted on the shaft and held in adjusted angular andlongitudinal. position by I a. set screw 29. The upper end of the armcarries I a vertical studtii on whichis rotatably. mounted a roll 3|.Mov'ementof the rollto the right in Fig. 2by shuttle presence willacttodepress the dagger and cause it to clear the hunter as the laymoves forwardly, or to theleft inFig. 2. A

torsion spring 34 surrounds rod 18 and has one end 35 under the .lay' l0and the other end 36 40 under the dagger IE to lift the latter and alsourge the protector roll 3| to the left, or toward the The back of thebox is formed inpart by a continuous belt 40 having anouter verticalface v M. Inner and outer guide wheels or pulleys 42 and '43,respectively, are mounted 'rotatably on the lay so that the beltmaytravel in adirection substantially parallel to'the. shuttle. Toaccomplish this result,- a stand -44 on the outer endof I A second Istand 46 for the inner pulley 42 is also on the lay and carries a stud41 to which is keyed as at 48 a clutch member 49. The latterhas in thisinstance threenotches 5!] which define wedge shaped pockets 5| with theinterior surface 52 of wheel 42. I

Clutch pins 53 are located in the pockets and are the means foreffecting a holding connection between the pulley 42 and the fixedclutch member. As shownin Fig. 5, the pins are supported by the stand46, and the engaging concentricpartsi-of'ithe pulley 42- and clutchmember are cylindricahso 'that the latter may "be reversed. I

When the loom is running at a high speed, it is desirable to checktheushuttle effectively and also protect as early as possible toallow'time for stopping. Under these conditions, as the shuttle entersthe box, it will engage the belt which will be bent inwardlybyspring"34' acting through the roll as shown in fulllines inFigJ'l. Theclutch and pins will act tO-z'lBSlSt movement of the belt around thepulleys so thatchecking of the shuttle may result. As theshuttle'conntinues tolrmove itvwillopushi the :-belt rearwardly,:zstraigh'tening itxout tothedotted line position oflrzandathereby-moving the:roll 3 l rearwardly or to the right as seen inFig. 2. The loom will ;thereforercontinue tor'run. Failure of the uttleto enter the box will leave the roll 3| in forward .iposition, [withresultant. loom: stoppage.
